Question

我有一个Web服务，它接收complexType Pic的对象，

Pic.java

public class Pic implements KvmSerializable{

    private double latitude;
    private double longitude;
    private long time;
    private double accuracy;
    private String name;
    private byte[] imageInByte;

    public byte[] getImageInByte() {
        return imageInByte;
    }
    public void setImageInByte(byte[] imageInByte) {
        this.imageInByte = imageInByte;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public double getLatitude() {
        return latitude;
    }
    public void setLatitude(double latitude) {
        this.latitude = latitude;
    }
    public double getLongitude() {
        return longitude;
    }
    public void setLongitude(double longitude) {
        this.longitude = longitude;
    }
    public double getAccuracy() {
        return accuracy;
    }
    public void setAccuracy(double accuracy) {
        this.accuracy = accuracy;
    }
    public long getTime() {
        return time;
    }
    public void setTime(long time) {
        this.time = time;
    }

    @Override
    public Object getProperty(int arg0) {
        switch(arg0){
        case 0:
            return latitude;
        case 1:
            return longitude;
        case 2:
            return time;
        case 3:
            return accuracy;
        case 4:
            return name;
        case 5:
            return imageInByte;
        }
        return null;
    }
    @Override
    public int getPropertyCount() {
        return 6;
    }
    @Override
    public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
        switch(arg0){
        case 0:
            arg2.type = PropertyInfo.STRING_CLASS;
            arg2.name = "latitude";
            break;
        case 1:
            arg2.type = PropertyInfo.STRING_CLASS;
            arg2.name = "longitude";
            break;
        case 2:
            arg2.type = PropertyInfo.LONG_CLASS;
            arg2.name = "time";
            break;
        case 3:
            arg2.type = Double.class;
            arg2.name = "accuracy";
            break;
        case 4:
            arg2.type = PropertyInfo.STRING_CLASS;
            arg2.name = "name";
            break;
        case 5:
            arg2.type = MarshalBase64.BYTE_ARRAY_CLASS;
            arg2.name = "imageInBytes";
        default:
            break;
        }
    }
    @Override
    public void setProperty(int arg0, Object arg1) {
        // TODO Auto-generated method stub
        switch(arg0){
        case 0:
            latitude = Double.parseDouble(arg1.toString());
            break;
        case 1:
            longitude = Double.parseDouble(arg1.toString());
            break;
        case 2:
            time = Long.parseLong(arg1.toString());
            break;
        case 3:
            accuracy = Double.parseDouble(arg1.toString());
            break;
        case 4:
            name = arg1.toString();
            break;
        case 5:
                imageInByte = Base64.decode(arg1.toString(), Base64.DEFAULT);
                    break;
    default:
            break;
        }
    }
}

我通过在信封双打和marshalBase64中注册将其发送到网络服务。到目前为止一切运行顺利，虽然在Web服务中，一旦我得到对象方法picture.imageInByte（）返回null。我不确定发生了什么，因为我可以像这样传递一个byte []变量并将文件写入磁盘。但我只传递一个byte []而不是一个带有byte []的复杂对象。

有什么问题？

Answer 1

我解决的方法是改变Web服务以接收2个参数而不是一个。

像这样：

public void receivePicture(Pic picture, byte[] image){

}

其中picture是我需要的关于图像本身的信息，而image是实际的图像文件。

我知道这是一个黑客，而不是我正在寻找的好解决方案，但它有效。
